Description
Technical Field
The invention relates to the field of biomedical material processing and preparation, in particular to a protein aqueous solution spraying device.
Background
The silk fibroin is extracted from silk or spider silk, has wide source, convenient and diverse processing, and excellent mechanical property, biocompatibility and biodegradability of the product. The silk fibroin is easy to denature under the influence of temperature, humidity, stress and concentration, so that the preparation method of the coating is limited. The silk fibroin film is usually prepared by sol-gel method, spin coating method, coating-evaporation method, etc.
Due to the changeability of silk fibroin, basically all the coating methods of silk fibroin coatings are biased to simply coat the silk fibroin aqueous solution on the surface of a sample. However, these methods inevitably have several disadvantages: (1) firstly, the film layer is not easy to accurately control the thickness due to the adoption of the modes of coating, casting, soaking and the like, and the film layer obtained by the method is easy to crack and fall off; (2) if the vertical lifting mode is adopted for dip coating, the uniform coverage of the coating is difficult to achieve due to the influence of gravity and the surface tension of the liquid; (3) because the coating raw material is liquid and directly contacts the surface of the sample, the coating raw material is difficult to achieve finer texture, and meanwhile, the coating raw material is remained on the surface of the sample by depending on the viscosity of the liquid, and the defects can be further amplified in the coating process aiming at the unconventional plane sample; (4) the coating solution is easily influenced by temperature and humidity, and is easy to generate a gel phenomenon in the using or storing process, so that the preparation efficiency is reduced; (5) in the forming stage of the coating, the water evaporation of the silk fibroin solution sprayed on is slow, the natural airing takes long time, and the silk fibroin solution is not suitable for mass production.
Spraying is a common coating preparation technology and is widely applied in industry, but in spraying of a silk fibroin coating, the silk fibroin solution is influenced by temperature, humidity and drastic airflow change in a spray gun, so that the silk fibroin structure is easily changed, flocculent precipitates or gel substances are generated, and liquid stored in a spray gun tank is often denatured into gel due to the influence of humidity and temperature, so that pipelines are blocked. Meanwhile, when an inorganic material is added into the silk fibroin solution to realize a specific function, the inorganic material and the silk fibroin solution are fused in a physical state, so that the inorganic material is separated from the silk fibroin solution under long-time precipitation, and the obtained coating cannot achieve the expected effect.
